bdevperf: Factor out getting free task from io_target to a function

Browse Source 
This patch and the next patch will simplify the nesting of task
submission.

Factor out the operation to get free task from io_target into a
helper function bdevperf_target_get_task(). Use
bdevperf_target_get_task() in bdevperf_submit_single() and
reset_target().
